A duck nesting box provides a home for female wood ducks and other cavity-nesting species in wetlands where natural cavities are scarce. Wood ducks prefer natural tree holes, but in the absence of such sites they will use man-made structures such as abandoned woodpecker holes or natural voids in trees resulting from fire, lightning or disease. Deployment of large numbers of artificial nesting cavities can significantly augment local wood duck populations and enhance the success of wild duck management programs in areas where natural cavities are unavailable.

Designed to mimic natural a tree hole, wood duck boxes are constructed from a variety of materials including rough-cut lumber, plywood, cedar and even fiberglass and plastic. The type and material of a nesting box is usually determined by the desired habitat in which it is placed. In areas where flooded forest wetlands are the dominant feature, a box constructed of rough-cut pine or cypress is recommended. For more remote ponds, a box made of sturdier, rough-cut lumber, such as spruce or oak, is typically preferred.
 https://nestvui.com/to-yen-vun-tinh-che/ nesting boxes were credited to biologists Gil Gigstead and Milford Smith, who in 1937 erected 486 bark-covered slab wooden next boxes at Chautauqua National Wildlife Refuge in central Illinois. Since then, millions of wood duck boxes have been erected across the nation by a wide variety of individuals and groups from wildlife agencies to conservation-minded private citizens.

When constructing a wood duck nesting box, proper entry hole dimensions are critical. To ensure that the hole is square and the correct size, you can use anything with a straight edge to mark a line (square, ruler, spare board) and then cut out the hole using a handsaw or jigsaw. To aid in your cutting, it is helpful to drill a pilot hole through each piece of lumber prior to beginning the cut.

Once the nesting hole is drilled, it's necessary to score the inside face of the front (4) with horizontal slots for toe holds when ducklings climb out of the box. These horizontal grooves are also important for helping hens grip the sides of the box as she takes her eggs to and from the nest.

Ideally, the entrance flyway to the nesting box should be on or near water (ponds, creeks, beaver ponds or small lakes). Nest boxes should be placed six feet high on land and three feet above historic high water levels in water.

It's also a good idea to place a predator cone below the nesting site. This will help to discourage raccoons and other animals from attacking the birds and their young, as well as other predators such as squirrels and skunks that are known to raid nests for eggs and young. Finally, the area around a wood duck box should be free of low hanging limbs and brush that could invite snakes and other varmints to ambush approaching ducks or hens incubating eggs.
